Walter E. Nicholson Jr. INVfiNTOR. l0 9 BY Wm WWW m 2 737,836 IC iatented Mar. 13, 1956 2,737,836 PAPER CORE REPAIRING TooL Walter E.Nicholson, In, Philadelphia, Pa. Application September is, 1952, SerialNo. 310,191 1 Claim. (Cl. 81-15 This invention relates in general totools, and more specifically to a paper core repairing tool.

The primary object of this invention is to provide an improved tool forstraightening tubes and the like, said tool being provided with aplurality of heads for progressively straightening the tubes.

Another object of this invention is to provide an improved tubestraightening tool which includes first and second tube straighteningmembers having elongated handles, said tube straightening member beingof different sizes and being adapted to be progressively passed throughtubes whereby the same may be gradually straightened.

A further object of this invention is to provide an improved tubestraightening tool which includes first and second tube straighteningmembers having elongated handles which are in telescoping cooperatingengagement, said tube straightening members being adapted to be forcedthrough a bent tube for straightening the same by utilizing the handleof the other tube straightening member as a ramrod.

A still further object of this invention is to provide i an improvedtube straightening tool which includes first and second tubestraightening members having elongated handles, said tube straighteningmembers adapted to have their handles telescoped so as to form a compactand an easily handled unit.

Figure 1 is a plan view of the tube straightening tool, which is thesubject of this invention, one of the handles of the tube straighteningtool being shown in section in order to clearly illustrate the manner inwhich its tube straightening member is secured thereto and therelationship of the other handle which is telescoped therein, thecentral portions of the handles of the tube straightening tool beingbroken away;

Figure 2 is a plan view of one of the tube straightening members and itsassociated handle, a portion of the handle being broken away adjacentits intersection with the tube straightening member in order toillustrate the manner in which the same is secured to the same, anintermediate portion of the handle being broken away;

Figure 3 is a plan view of the other of the tube straightening memberand its associated handle, the handle having intermediate portionthereofomitted;

Figure 4 is a transverse vertical sectional view taken substantiallyupon the plane indicated by the section line 44 of Figure l and showsthe cross sections of the bandles and one of the tube straighteningmembers; and

Figure 5 is a transverse vertical sectional view taken substantiallyupon the plane indicated by the section line 5-5 of Figure 2 and showsthe general cross section of the other of the tube straighteningmembers.

Similar characters of reference designated similar or identical elementsand portions throughout the specification and throughout the difierentviews of the drawings.

Referring now to the drawings in detail, it will be seen that there isillustrated inFigure 2 a first tube straightening member, which isreferred to by the reference numeral and which is conical in outline.Extending rearwardly from the b ase of the tube straightening member 10is a rod-like extension of a reduced cross section. The rod-likeextension is referred to by the reference numeral 12 and is utilized inthe securement of the tube straightening member 1 0 to an elongatedhandle 14. The handle 14 is preferably of a circular cross section andhas formed in one end thereof a circular cross sectional bore 16 of asize to tightly receive the rod-like member 12. It will be understoodthat the rod-like member 12.may be forced into the bore 16 so as toprevent separation of the handle 14 from the tube straightening member10. However, if additional fastening meansshould be deemed necessary,the handle 14 may be secured to the tube straightening member 10 bysuitable fastening means.

The tube straightening member 10 and its associated handle 14 forms afirst tool section which is referred to in general by reference numeral18. The tube straightening tool, which is the subject of this invention,is referred to in general by the reference numeral 20 and includes asecond tool section which is referred to by the reference numeral 22.The tool section 22 includes a tube straightening member 24 which isalso conical in outline, but is of a smaller size than the tubestraightening member 10. The tube straightening member 24, as is bestillustrated in Figure 1, is also provided with a rod-like member 26which is of a reduced cross section and extends rearwardy from the tubestraightening member 24.

The tool section 22 also includes an elongated handle 28 which istubular and is formed of pipe or the like. The handle 28 has an internaldiameter substantially equal to the external diameter of the rod-likeextension 26 and the same is forced into one end thereof. The tubestraightening member 24 may be additionally secured to the handle 28, ifit be necessary, by suitable fastening means.

It will be noted that the external diameter of the handle 14 issubstantially equal to the internal diameter of the handle 28 whereby asliding telescoping fit is permissible. It will be also noted that thelength of the handle 14 is such that the free end thereof engages theend of the rod-like extension 26 simultaneously with the engagement ofthe free end of the handle 28 with the base of the tube straighteningmember 10.

When it is desired to straighten a tube having a flat tened portion, thetube straightening member 24, which is the smaller of the tWo tubestraightening members, is started into one end of the tube to bestraightened. Then by utilizing the tool section 18 as a ramrod, thetube straightening member 24 is forced through the tube beingstraightened. After the tube straightening member 24 has been forcedthrough the tube, the same is withdrawn from within the tube and thetool 20 reversed end for end. The tube straightening member 10 is thenaligned with and forced into the tube to be straightened. The tubestraightening member 10, which should have a diameter substantiallyequal to'the diameter of the tube being straightened, is thenprogressively forced through the tube by utilizing the tool section 22as a ramrod. Inasmuch as the tube straightening member 10 has a diametersubstantially equal to the diameter of the tube being straightened, itwill be seen that when the tube straightening member 10 is forcedthrough a tube, the internal diameter thereof is returned to normal.Having been so straightened, the tube may be utilized for the purposefor which it was intended.

While the tube straightening tool 20, which is the subject of thisinvention, may be utilized with any type of tubes, the tool has beenspecifically designed for repairing paper rolls that have been damagedso that the center is flattened together in such a condition that theroll cannot be mounted on a shaft. By utilizing the tool 20, in themanner outlined above, the core of the paper rolls may be opened toallow the shaft to be inserted therethrough.

The operation of this device will be understood from the foregoingdescription of the details thereof, taken in connection with the aboverecited objects and the drawings. Further description would appear to beunnecessary.

Minor modifications of the device, varying in minor details from theembodiment of the device illustrated and described here, may be resortedto without departure from the spirit and scope of this invention, asdefined in the appended claim.

Having described the invention, what is claimed as new is:

A tube straightening tool comprising a pair of members, each of saidmembers having a handle portion and an enlarged head portion, one ofsaid handle portions being tubular and having the other of said handleportions telescoped therein, one of said head portions being in the formof a conical tube straightening head, said conical head having a base ofa greater diameter than the diameters of said handles, the other of saidhead portions being in the form of a driving head.
